How to Remove Blank Pages from PDF Online
(2026 Step-by-Step Guide)
Let me tell you about the 47-page PDF that was really only 23 pages
A client sent me their annual report to print. 47 pages. I hit print. 47 sheets came out. But pages 2, 4, 6, 8, and about 20 others were completely blank. I wasted paper, ink, and time. Turns out their scanner inserted a blank page between every single document section. This happens all the time. Office scanners, double-sided printing, merged PDFs - blank pages sneak in everywhere. The good news? Getting rid of them takes about 30 seconds.
Why Do Blank Pages Keep Appearing in My PDFs?
Scanner Insertion
Office scanners are too smart for their own good. They detect when you lift the lid or when there's a gap between documents, and they insert a blank page as a separator. Helpful? No. Annoying? Yes.
Fix: Remove every other page? Not always. Preview first. Sometimes it's every 3rd page, sometimes random.
Double-Sided Printing Artifacts
When you print double-sided and your document has an odd number of pages, the printer adds a blank page at the end so the last sheet isn't single-sided. Then you scan that document, and the blank page comes along for the ride.
Fix: Usually just the last page. Check and delete.
Merged PDF Separators
Some PDF merger tools add blank pages between documents by default. Why? No idea. But they do. You merge three PDFs and suddenly you have two extra blank pages you never asked for.
Fix: Preview before merging, or remove after.
Word/Excel/PPT Exports
Export a PowerPoint presentation as PDF. Now there's a blank page at the end. Export a Word document that had a stray page break. Blank page appears. Export an Excel sheet that calculated an empty range. Blank page.
Fix: Clean up source document, or just delete after export.
The real problem
Blank pages aren't just annoying - they cause real problems. You print 50 pages when you only need 40. You send a client a document with random empty pages that look like mistakes. You upload to a portal that counts pages and rejects your submission. You waste time scrolling.
How to Remove Blank Pages (30 Seconds, No Software)
Step 1: Upload Your PDF
Find a tool that lets you preview pages before deleting. Drag and drop or click to select. The best ones process everything in your browser - no server uploads, so your documents stay private.

Step 2: Preview and Identify Blank Pages
Good tools show you thumbnails of every page. Blank pages are obvious - just white rectangles. Some tools even auto-highlight pages with no content.
Step 3: Select and Delete
Check the boxes on blank pages (or use "Select All Blank" if available). Click Delete. The tool removes them instantly. Your remaining pages renumber automatically.
Step 4: Download Clean PDF
One click downloads your cleaned file. No blank pages, no wasted space, no awkward empty sections. Ready to print, share, or upload.

The "Almost Blank" Problem: Pages That Look Empty But Aren't
Watch out for these imposters
White text
Someone typed text, changed the color to white, and now it's invisible on screen but still technically content. Tools that only check for "empty" might miss this.
Tiny watermarks
A small logo, a faint "DRAFT" stamp, or a page number in the corner. The page isn't blank, but you might still want to remove it.
Hidden metadata
Invisible layers, comments, or annotations. The page looks empty but has hidden data. Some tools detect this, some don't.
Blank but intentional
Sometimes blank pages are there on purpose - like a "Notes" page or intentional divider. Don't auto-delete everything without checking.
Solution: Use tools that show you the actual page content, not just a "blank/not blank" flag. Preview before deleting. When in doubt, keep it.
Real Problems I've Fixed (And What They Taught Me)
The University Application Disaster
A student needed to upload her transcripts to a university portal. The portal had a strict page limit - 10 pages maximum. Her scanned transcript PDF was 18 pages. Six of them were completely blank - inserted by the scanner between each semester. She removed the blank pages, got down to 12 pages. Still over the limit. Removed the coversheet and instructions. 9 pages. Application submitted successfully.
Lesson learned: Page limits are real. Blank pages count against them. Always check before uploading.
The Client Presentation Embarrassment
A consultant prepared a 40-page pitch deck. Sent it to the client for review. The client printed it on their fancy office printer - double-sided, booklet format. Every even-numbered blank page made the print job look like a mistake. The client asked if the document was "still in draft." Not a good look.
Lesson learned: Always clean your PDF before sending to clients. Blank pages look unprofessional, even if you know they're harmless.
The E-Book Reading Nightmare
Someone bought a technical e-book. Converted PDF to read on tablet. Every chapter started on a right-hand page, which meant every chapter was preceded by a blank left-hand page from the previous chapter. Reading meant swiping through blank screen, content, blank screen, content. Removed all blank pages, reflowed the content, read smoothly.
Lesson learned: Digital reading doesn't need physical book formatting. Blank pages are useless on screens.
Should You Manually Select Pages or Use Auto-Detect?
Manual Selection
You look at each page and decide. Takes longer but you have complete control.
Best for: Short documents, important files, pages with subtle content
Auto-Detect
Tool identifies blank pages for you. You review and confirm. Fast and accurate.
Best for: Long documents, scanned files, regular cleanup tasks
My approach: Auto-detect, then quickly scroll through the detected pages to confirm. Takes 10 seconds and catches everything.
Important: Keep Your Documents Private
Your PDFs contain sensitive information
Contracts, resumes, financial reports, personal documents. You shouldn't upload these to random websites that store your files on their servers.
Look for tools that:
- Process files in your browser
- Never upload to external servers
- Delete files immediately after you're done
- Don't require account creation
If a tool asks you to "upload" and then gives you a shareable link, your file is on their server. Anyone with the link might access it. Be careful with sensitive documents.
